摘要
提出采用旋转填料床/臭氧/超声法处理染料废水的方法,考察了超重力因子、pH、处理液量及处理时间等因素对脱色率和COD去除率的影响。结果表明用旋转填料床/臭氧/超声法处理染料废水10min,脱色率达98%;处理30minCOD去除率达81.8%,其处理效果明显高于鼓泡反应器/臭氧/超声波法。
A method of treating dye wastewater is applied with rotating packed bed（RPB） in order to intensify ozone/ultrasonic. The effects of high gravity factor （fl）, pH, flow rate and reaction time on discoloring and COD removal efficiency are investigated. The results indicate that the ozone/ultrasonic treatment in a rotating packed bed can result in a dccoloration efficiency of over 98% after 10 min, and the COD removal efficiency of 81.8% after 30 min ,which means RPB/O3/US is better than BR/O3/US in efficiency.
